THE MAJOR RESET OPTIONS DO NOT WORK IF THIS IS OCCURING BECAUSE YOU CANNOT ACCESS ANY OPTIONS ON YOUR HOME SCREEN!!! (i.e. Applications > Settings, etc.)

My phone is stuck on "Downloading... Do not turn off Target!!!" and whenever i restart, i encounter the same problem and when i repeat the action, the same thing happens. There HAS to be another way to reset this phone. I JUST got it recently. It should not be malfunctioning already.

i am having an issue with my samsung galaxy S....none of my apps will show up on the screen, the only thing i can do is text and call. my phone vibrates and this is what comes up; "com.sec.android.app.twlauncher has stopped unexpectedly" it wont let me reset my phone.
